Guidance and manufacturer’s declaration – electromagnetic immunity
The “Mini Daylight” is intended for use in the electromagnetic environment specified below. The customer or
the user of the “Mini Daylight” should ensure that it is used in such an environment.
Immunity test
IEC 60601

Electromagnetic environment –
guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the “Mini Daylight”, including cables,
than the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
3 Vrms
150 kHz to 80 MHz
d=1.2 P

d=2.3 P 800MHz to 2.5 GHz

where P is the maximum output power rating
of the transmitter in watts (W) according
to the transmitter manufacturer and d is
the recommended separation distance in
metres (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
survey, a should be less than the compliance
level in each frequency range.b
Interference may occur in the vicinity of
equipment marked with the following
symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically
with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic
site survey should be considered. If the measured field strength in the location in which the “Mini Daylight” is
used exceeds the applicable RF compliance level above, the Medical Daylight should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the “Mini Daylight”.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
